(Cl. 13d-304) 1d) Claims.

This invention relates to improvements iin take-ups for looms and it isthe general object of the invention to provide a take-up drive which canbe operated either automatically by the loom or manually.

The cloth in a loom is led from the weaving point to a roughened take-uproll which is driven during loom operation to pull the cloth forwardly.A train of gears is connected to the take-up roll and is driven by somepart of the loom at the proper rate to advance the cloth as it is woven.During normal weaving operations the take-up is driven forwardly butshould a inispick occur necessitating removal of any picks of weft fromthe fabric the take-up roll is reversed so that the fell of the clothcan be moved rearwardly. Y

It has been proposed heretofore to operate the take-up roll by a wormwheel meshing with a' worm driven by power derived from some part of theloom, such as the upright shaft of the Knowles head customarily used onworsted looms. 'Ihe worm has formerly been connected to a forwardlyextending take-up shaft carrying a hand wheel by which the worm and itsworm wheel could be manually reversed. It is an im` portant object of mypresent invention to mount the hand wheel on a sleeve carrying the wormand provide the hand wheel with a handle normally in meshing or drivingrelation with a driving wheel on the forward end of the take-up shaftwhich passes through the sleeve. The handle is constructed in such amanner as to reduce wear of itself and the part of the hand wheel whichit engages.

It is another object of my present invention to provide the handle withmeans for pivotally connecting one end of it to the wheel andconstructing the other end of the handle so that it will engage a partof the wheel and assist in holding the handle substantially fixed withrespect to the hand wheel to provide an improved driving connection withthe aforesaid driving wheel.l

It is still a further object of my invention to provide the hand wheelwith two similar pockets either of which can receive the pivoted end ofthe handle while the other receives the outer end of the handle. Thisfeature of my invention permits reversal of the handle with respect tothe pockets when objectionable wear has developed. No matter whichpocket provides the pivotal support for the handle however the oppositepocket will receive the outer end of the handle to assist tween theshaft and the worm.

- It is a more particular object of my present invention to provide aloom take-up hand wheel having diametrically opposite pockets the lowerpart of each of which can receive the pivoted end of the handle whilethe upper part of each pocket can each receive and have engagement withthe outer end of the handle. By this arrangement any wear which developsin one of the pockets adjacent the pivoted end of the handle will liebelow that part of the pocket which engages the outer end of the handlewhen the latter is reversed. The result of this construction is to causethe opposite ends of the handle to engage different parts of the pocketsso that upon reversal of the handle its ends will engage unworn surfacesof the pockets.

Withv these and other objects in view which will appear as thedescription proceeds, my invention resides in the combination andarrangement of parts hereinafter described and set forth.

In the accompanying drawing, wherein a convenient embodiment of myinvention is set forth,

Fig. 1 is a side elevation of part of a loom having my invention appliedto the take-up thereof,

Fig. 2 is an enlarged front elevation in the direction of arrow 2, Fig.1, `showing the hand wheel and its handle in normal driving position,

Fig. 3 is a section on line 3-3 of Fig. 2 showing the handle in forcetransmitting position in full lines and in dotted lines for manualturning of the hand wheel and its worm, and

Fig. 4 is a transverse section on line 4 4 of Fig. 3.

Referring particularly to Fig. 1, I have shown a loom frame I0 having apattern mechanism K driven by an upright shaft II and the usual gearingindicated generally at I 2 for the shaft. This gearing includes a sleeveI3 which is normally down but which can `be raised in the usual mannerby mechanism I A. Extending forward` ly from the mechanism I2 is atake-up driving shaft I5 journaled at I6 with respect to the loom frameand having the forward end thereof surrounded by a sleeve Il. A worm I8on the sleeve meshes with a worm wheel I9 rotatable about an axis 20 andgeared by mechanism not shown to the take-up roll and its train ofgearing. A hand wheel 2I is provided for turning the sleeve Il and wormI8.

The matter thus far described is of usual construction and may ifdesired take the form shown in the following prior patents: McGuiness t737,002; Ryon 886,871, and 1,552,651.

In carrying' my invention into effect, I provide an improved drivingconnection between a takeup shaft I and the sleeve I'I, this drivingconnection comprising a handle H mounted pivotally on the wheel 2| andmovable into and out of driving connection with the shaft I'I. Referringmore particularly to Figs. 2 and 3, the wheel 2| has a continuousv rim25 and a hub 26 held to the sleeve I'| by a set screw 2.1 and connected.to the rim 2| by two spokes 23. Two other spokes 30 and 3| formed inaccordance with my present invention also connect the hub to the rim.

Spoke 30 has two spaced walls 32 and 33 between which extends a pocketor slot 34 which is substantially radial with respect to the axis of thewheel 2|. A pivot pin 35 extendsv through the walls 32 and 33 and acrossthe slot 34 at a point displaced rearwardly from the plane of rim 2|,the front of the loom being at the right of Fig. l. In similar mannerthe spoke 3| has spaced walls l0 and 4I separated by a. pocket. ors101142 4across which extends a, pivot pin #i3 held by the adjacent.walls. The two spokes: 3i] and- 3| and the pivot pins are substantiallythe same and: the slots 3.4: and 42 are diametrically opposite.

The take-up shaft I5 has keyed thereto asat 4,1: a driving or clutch.wheel I8 having several peripheral notches. 49. each one: of which. isypro,- portioned to` receive a driving or clutching lug 55.- on` thehandle H. When the parts are inv the positionr shown in full lines in.Fig. 3, the lug will be in onev of the notches and as the shaft I5'turns the driving wheel 48 will turn` the lugV 5d,- and handle, aroundthe. shaft axis.

The handle is` formed more particularly as shown in Figs.A 2 and 3 andcomprises; a. body 55 shaped to afford a hand hold. One end of thehandle is flattened` as at 55 and is of such a width as to ft snuglyinto either of the pockets or slots 34 and 42. This end of the handlieisprovided with aA bore 5l to receive one or the other oi the pivot pins35 and 43. Flattened sur.- faces 543 and 59 angularly disposed as shownin Fig. 3` are adapted for engagement with the head 50 of a springplunger mounted in the rearpart; of the spokes 3l) and 3| at the bottomsofA the pockets or slots 3.4 nad 42.. It is to be under stood that thespring plungers are similar` and that one is provided for each of theslots 34 and 42;. Underl normal conditions onel of the spring plungerswill engage the surface 59 to hold the. handle I-I inr idle position.-preferably within the outline of the hand wheel 2 I, but the. handle canbe moved to the dotted line position in Fig. 3 against the. action ofthe associated spring plunger and the head of the latter will thenV holdthe handle in proper position for manualturing of the wheel.,

That end 55 of the handle H which is opposite the flattened end is ofsuch size as, to t snugly into one or the .other of the slots 3.4 or42.. It. will be seen from Fig. S that the reduced end 55 engages thoseparts of the adjacent walls which are forward of the parts ofthe; wallwhich can bei engaged by the flattened part 55` of the handle.

Assuming that the parts are in the position shown in Fig. 2, the rearpart of slot 3.4 will ree ceive the flattened'end while the front partiof slot 42 will engage the end 65 of the handle. The handle is thereforeheld firmly in the two pockets of the hand wheel, extending across itsdiameter and firmly placing the lug 5U in one of the driving notches 49.The driving force ofthe shaft I5 is therefore transmitted from thedriving wheel 49, through the lug 50 and the handle H, to the wheel 2|,both ends of the handle assisting in this transmission of force. Thehandle end 65 reduces vibration of the flat end 56 of the handle to aminimum, but after long continued use the parts of the walls 32 and 33which engage the, handle develop Wear. When this occurs the pins 35 and43 are removed and the flat end 56 of the lever taken out of slot 34 andinserted into slot 42, after which the pin 43 is replaced to establishpivotal connection between the handle and walls and 4|.

Any wearing of the walls 4|) and 4I in the iirst setting of the handledue to movement of the handle end 65 will occur at the front end ofpocket 42 only, and the flattened end 56 of the handle in its newposition will fit into the rear part of the slot 42. which was notpreviously worn by the handle end 65. In like manner, the end 65 will belocated in the front. end of slot 34, which did not have previousengagement with the flat end 56 of the handle. The handle in, its, newvsetting therefore engages surfaces which it did not. en gage in itsprevious setting. The lug will' be able to t into one or another: of thenotches 49 when the handle is thus; reversed.

From the foregoing it willbe seen that I have provided an improved handwheel and handle. serving as a drive between the shaft I5 and the. wormI8 so constructed that the handle I-I when in normal position engagesopposite sides of the wheel to drive the latter uniformly and preventjarring and objectionable motion between the pocket walls andthe ends ofthe handle. It will also be seen that the handle is reversible due tothe construction and proportions of its ends and that the lug 5! willhave driving relation with respect tothe drive wheel 48 when the handleis in either of its positions. be noted that the flattened endengagesthe; rear parts only of the pockets 34 and 42 whereas. the handle endengages the forward parts only of said pockets', hence the wear producedby one end of the handle inthe pocket does notI interfere with theproper fit of the other endv ofthe handle` when the latter is reversed.

Havingv thus described my invention it will be. seen that changes andmodiiicati'ons may be made therein, by those skilled in the artwithoutdeparting from the spirit and scope of the invention and I do not wishto be limited to' the details. herein disclosed, but what Iclaim is:
